//! Drops in the API (oxygenhub#279): `GET`/`POST /drops` (yours; making
//! one), `GET /users/{name}/drops` (someone's public ones),
//! `GET`/`PATCH`/`DELETE /drops/{id}`. Reading a drop needs nothing but
//! its id; changing one needs `repo:write` and to be its owner (or a site
//! administrator, who may also delete it). Forking, starring and comments
//! (oxygenhub#349) need `repo:write` and an account, as on the web.
